● Adopt an electronic stethoscope that can automatically identify the auscultation sites. Use the "non-contact landmark
network" technology to completely cover each auscultation site and auscultation area. Through the identification and
management of logic programs, intelligent auscultation is achieved and the electronic stethoscope is placed on the
simulated human body. Any of the auscultation sites can hear their respective physical signs, like physical examination on
real patients; more than 150 physiological and pathological signs of common cardiovascular examinations and more than
80 chest and lung examination signs are collected.

● Cardiac auscultation: vividly reproduce nearly one hundred kinds of heart sounds. besides five common cardiac
auscultatory valve areas, the system is equipped with “interior cardiac apex auscultation site”, “lateral cardiac apex
auscultation site”, and “the fourth intercostal space on the left sternal border” auscultation site, available to hear pericardial
friction, pericardial knock, etc.; with cilinical breath sounds auscultation sites and “non-contact landmark network”
technology, the system realizes auscultation of full lungs (including manikin’s back), and all breath sounds in left anterior
chest accompanied with corresponding heart sounds. A shock sensor is used to simulate diastolic fine tremor, systolic fine
tremor and continuous fine tremor; newly added "apical beat" to simulate the "change in the apical position" of the organic
heart disease, which deepens the description and understanding of the heart sounds production mechanism; besides
simulation of mitral insufficiency and aortic stenosis murmur conduction auscultation, newly added “pulmonary artery
stenosis murmur conduction”, and murmurs become weak gradually with extension of conduction distance.
